LINETRAXX® VMD461

Product catalog summary

Product Overview: The LINETRAXX® VMD461 is a versatile voltage monitoring relay for AC, DC, and 3(N)AC systems. It monitors various parameters such as underfrequency, overfrequency, overvoltage, undervoltage, phase sequence, unbalance, vector shift, and ROCOF. It provides real-time measurements and stores alarm-triggering values.

Key Features:

Monitors DC systems up to 1200 V and AC systems up to 690 V with the CD440 coupling device.
ANSI code representation for all functions.
Includes unbalance, phase failure, and phase sequence monitoring.
RS-485 interface for data exchange and parameter setting.
Backlit graphic LC display and password protection for settings.

Applications:

Monitoring voltage-sensitive machines and installations.
Protecting three-phase motors and transformers.
Islanding and vector shift detection for electrical machine protection.

Functional Description: The device has a start-up delay upon receiving supply voltage, during which alarm relays are unaffected by changes in measured values. It features adjustable voltage and frequency limits with response delays. Exceeding limits triggers relay switching and LED indicators.

Standards Compliance: Complies with DIN EN 60255-127, VDE 0435-3127, and UL File: E173157.

Technical Specifications:

Rated voltage: DC, 3AC up to 1200 V; 1AC, 3NAC up to 690 V.
Operating temperature: -25 to +55 °C.
Protection class: IP30 for internal components, IP20 for terminals.
Connection types: Screw-type terminals for VMD461, push-wire terminals for CD440.

Operating Elements: Includes LEDs for power and alarm status, a backlit display, and buttons for testing, resetting, and menu navigation.

Wiring and Connection: Provides detailed diagrams for connecting the VMD461 with the CD440 in various system configurations.

Additional Features: Supports remote shutdown, has a history memory for the last 300 network faults, and allows language selection among German, English, and French.
